Jake heard that spinning—rather than flipping—a penny raises the probability above 50\%50%50, percent that the penny lands showing heads. He tests this by spinning 101010 different pennies 101010 times each, so he's willing to treat these spins as a random sample. In his 100100100 spins, the penny landed showing "heads" in 686868 spins. He wants to use these results to test H_0: p=0.50H 0

Assuming that the conditions for inference have been met, calculate the test statistic for Jake's significance test.
